IMPROVEMENT IN DUMPlNG-CARS.

Specification forming part of Letters Patent No. 139,575, dated June 3,1873 application filed April 12, 1873.

To all whom it may concern:

Be it known that we, JOHN M. HANFORD and JOHN WOOD, of Middletown, inthe county of Orange and State of New York, have invented a new andvaluable Improvement in Dumping-Cars; and we do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this speci fication, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of an end view of ourdumping-car. Fig. 2 is a plan view of the same. Fig. 3 is a sectional,and Fig. 4 a side, view of the same.

This invention has relation tomeans for rapidly discharging the loads ofearth or coalcars, and it consists in the construction and novelarrangement of devices, whereby the two sections of the car are made totilt either toward the center or toward the outside of the bolsters,bottoms, sides, and pivoted arm, whereby the sides of each sections aremade to remain stationary, while the bottom is being inclined on oneside of the axis, and to rise with the bottom on the other side; and ofthe devices whereby the sides are secured to the bottoms, for receivingand holding the load securely.

In the accompanying drawings, the letter A indicates the truck-frame orframes, which may be constructed in the usual manner. B

B represent the bolsters, secured to the truck-frame at each end of thecar, and provided with suitable journal-seats a for the journals 1) ofeach section 0 of the dumpingcar. These journals are arranged at theends of the longitudinal beams D, which arecentrally arranged under thebottom E of each,

section. To the bottom E of each section is secured at each end asegment-board, F, which forms the end wall of each section. Transverselyunder the bottom of each section extend the catch-bars c, which projectsomewhat beyond the side edges of the bottom. The sides G of eachsection are longer than the bottom, and extend beyond it at Radial armsor braces 01 are secured to the sides at their ends, and are pivoted tothe bolsters 1n the ment-board, and to extend nearly to its middleportion. These guard-plates e serve to prevent the earth from escapingthrough the angular spaces between the rounded ends of thesegment-boards and the sides. To the outside of each of the sides G arepivoted above the catches c the hooks it. These are connected by ahorizontal rod, 9*, to which they are pivoted, and which is pivoted atits end to the operating-lever Z.

It is apparent that these sections can be made rigid and close for thereception of the load by securing the long sides G, which rest on.thebolsters, to the bottoms by means of the hooks h and catchers 0. Thesefastening devices should therefore be made in a substantial and strongmanner.

In dumping or discharging the sections the lever I should be operated tounfasten the hooks of the outer or inner side, according to the locationof the deposit, the outer hooks being loosed for a side discharge, andthe inner hooks for a center discharge. The bottom is then tilted, andthe side which has been unfastened remains stationary, while the bottomrotates downward and away from it on its axis. At the same time theother side wall, which has not been unfastened, rises with the bottom asit revolves upwards on this side. These movements are important, and thedevices employed in their production are simple and durable. It isapparent that the bottom of each section is secured in the levelposition by its attachment to the side pieces, which are in turn pivotedindependently to the bolster. The same result may be accomplished byvarious means well known to those skilled in the art, and, therefore, wedo not desire to confine our'claim to the precise means described.

What we claim as new, and desire to secure by Letters Patent, is-- 1.The combination of the bolsters, the centrally and longitudinallypivoted buttons, the
